GRAHAM D. TYSOR, OF SALEM, VIRGINIA, ASSIGNOR TO COMAS CIGARETTE MACHINE COMPANY, OF SALEM, 'VIRGINIA, A CORPORATION OF VIRGINIA.

v i To all whom it may concern Beit known that I, GRAHAM DI Tyson, of Salem, Virginia, have invented certain new and useful Improvements in Cutting Mechanism for Cigarette-Machines, of which the following is a-specificatlon.

This invention relates to improvements in 4 the cutting mechanism for cigarette machines and the object'of the invention is to.

' scribed and .then definitely claimed.

In the drawings accompanying and form ing part hereof: Figure 1 is a sldeelevation of the end of a cigarette machine containingmy improvements. Fig. 2 is a top plan view of the same.

Fig. 3 is an end elevation. Fig. 4 is asectional detail showing themounting for the rotary cutter. Fig.

5 is a perspective view of part of the gearin I l teferring now to the details ofthe drawings by numerals: -1 represents the main frame or table having slides 2 and 3thereon (see Fig. 3). The sliding frame 4 for carrying the cutter'is mounted to move back and forth upon the slides 2 and 3 and to give such motion to thecutter frame and its outter,- I connect said frame to a crank pin 6 by means of a link 8, this crank pin being adjustably connected to acrank disk lO shown 'in' Figs. 1 and 2. This crank disk is supported upon a vertical shaft 12 and-"is given rotary movement by gearinghereinafter de scribed. It is sufficient to here state that the revolution of the crank disk 10 will cause the cutter frame 4'to be moved back and. forth on the slides2 and 3, each IGVOlll'.

tion of ath'e crank disk moving the cutter frame once in each direction. The cutter frame 4 isprovided with standards 14 and 16in which is mounted-a shaft 18 to which is secured a pulley 20 driven by means of a belt 22 from a pulley 24 secured to the drive shaft 26. Upon the shaft 18 is mounted a knife carrying arm 28 having a knife shaft 30 journaled inone end thereof; this shaft Specification of Letters Patent;

having a pulley 32 and a rotary knife 34 secured thereon. The pulley 32 is connected by means of a belt 36 with a second pulley 38 secured to the aforesaid shaft 18. This construction results in motion being transmitted from the shaft 26 to the shaft 18 and from said shaft 18 through the belt 36 to the shaft 30 whereby the cutter 34 is continuously rotated. Therefore when the knife carrying arm 28 is in the position shown in Fig. 3, the cutter 34 will be in the act of cutting the cigarette. After the cigarette is completely cut, it is'necessary for the knife carrying arm 28 to be raised to move the rotary cutter 34 away from the cigarette. To accomplish this purpose the rear end of the knife carrying arm 28 is formed as will now be described. A second arm 40 is formed integrally with the knife carrying arm 28 and extends on the other side of the shaft 18. A third arm 42 is j ournaled upon the shaft 18 and the two arms 40 and 42 are connected together by a spring 44 so that in case of necessity one of these arms may move with respect to the other. The arm 42 is connected by means of a turn buckle arrangement 46 with a crank pin 48 driven in a manner to be described and as shown in Figs. 3 and 4. It follows from the construction above described that when the crank pin 48 moves downward, as seen in Fig. 3, the levers 40 and 42 will be likewise drawn downward so as to move the knife carrying arm 28 upward an'd'thereby move the rotary cutter in the same direction and away from the cigarette rod. However, during the other half of the movement of the crank pin 48 the turnbuckle is forced upward, thereby moving the levers 40 and 42 upward and at the same time'causing the rotary cutter 34 to move downward to again out the cigarette rod." The object ofthe two sets of arms 40 and 42 and the spring 44 is to prevent dam- For example, if there should be a small piece of'wire in the cigarette] rod or should any othe'r'obstruction loe in the path of theknife, the upward movement of the turn buckle'46 would move the arm 42'- upward and the spring 44 would also move the arm 40 with the arm 42 until the wire or other obstruction causes suflicient resistance to the downward movement of the 'k11ife34 to permit the spring 44 to Tie give, the result being that further upward movement of the turn buckle 46 will move. the arm 42 only, the spring 44 stretching and not moving the arm to the liinit of-its movement. "Thus, the rotary knife would.

v not be forced to'cut through a wire or any,

similar obstruction. 1i

' I'will now describefthe gearing for move:

ing the crank pin 48' and the crank disk 10 'togive simultaneous movement to'tlie knife carriage and to the rotaryknife. The drive shaft 26, hereinbefore referred to, isprovided' with a pulley 50 connected by a belt 52 with a pulley 54 on a main shaft 56.

This main shaft 56 drives the entire gearing for moving the knife downwardly at the same time that the knife frame is moved back and forth. To thisend the, mainshaft 56 is provided with a worm58 which meshes with and drives a worm gear 60 secured to l a shaft-62. Tothis shaft 62 is connected 'a gear 64jwhich meshes with'an idler gear 65 i g and drives a gear 66 on the counter shaft68.

Tov the shaft 68 is also secured a gear 70 which-rotates in the direction ofthe arrow shown in'Fig.'5 and this gear drives a gear 72 through an idler 7 4 shown in full lines o i'nFig 5. The gear 72 is looseIupon the "Shaft62 and has fixedly secured to it' a .worm 76 which meshes with and drives a worm gear 78 secured to the aforesaid Shaft 12 which gives movement tothe crank "disk 10. before described as giving" back, and

forth movement to, the knife carriage 4.; 'It follows from this construction thatiriotion is transmitted from the drive shaft 26-to the main shaft 56 and from this shaft 56 tothe gearing just described to the crankdisk 1O and that as said crank disk 10 is rotated, the knife carriage is movedfbhck and forth upon its slides 2 and 3. The main frame 7 of themachine also supports a standard 80 in which is journaled a shaft 82. carrying a the crank pin 48 hereinbefore, described for giving downward movement to the rotary cutter 34. This shaft 82 has connected to I oit a disk 84 whichis driven from the gear 66 hereinbefore describedf It will beobivis ous that any. connection between said gear journal the-shaft '82'eccentrically with respect toshaft 68'and connect the gear 66 with the disk 84 by means: of-alink shown in Figs. 1 and 3. Th s eccentric relation of the two shafts, and the-link ar rangeirient' for driving'the disk 8 4v from the gear 66 results in a quick dipping movemerit of the 'cutter 34 at ione'period of movement and a relatively slow movement dur ing thebalancebftlferotation.

The operation of ,nyf n1achine has been described so fully the description .ofthe' details that any further reference to the 1 operation is not necessary.

It is obvious that modifications and .Changesf nay be made in the construction, and arrangement of 'my nvention without departing from the spirit thereof, the'scope of whichis set forthintheappendedclaims.
